Filed: 1929-04-12
Abstract: 332,532. Piette, 0., and Union Chimique Belge, Soc. Anon. April 12, 1929. Catalytic apparatus; ammonia, catalytic production, of. - Apparatus for catalytic exothermal systbesis in the gaseous phase of the kind comprising a series of closedend tubes placed in the catalyst, each closed-end tube surrounding an inner open-end tube perforated at the lower part of its length, is so constructed and employed that the admitted gases descend between the closed-end tube and the inner perforated tube pass through the perforations in the inner tube and pass downwards through the catalyst. In an apparatus for the synthesis of ammonia the gas enters through an inlet 16 into a chamber 6, leaves at 17, and is adjustably distributed between tubes 19 and 20 by the cock 18. The gas in the tube 20 proceeds to the annular chamber 25, which is surrounded by an electrical resistance 9, by way of openings 22. The gas in tube 19 proceeds through the chamber 7 which surrounds the outlet 21 and the openings 22 to the annular chamber 25. The re-mixed gases proceed from the chamber 25 through the tubes 14 into the outer tubes 10. The downwardly proceeding gas escapes progressively through the openings 12 to proceed upwards through the inner tubes 11, through the openings 24 and down through the catalyst in the chamber 8 to the annular chamber 21 and the outlet 23.

Abstract: 216,659. Ziegenberg, R. April 27, 1923. Cells; electrodes; supports for; gas exits.-A cell having a soluble electrode is divided into two chambers by a partition T extending from the bottom nearly to the top, one chamber containing the electrodes P. Z. The electrolvte can be poured from one chamber to the other when it is desired to put the cell into or out of action, although the cell may be held upright in both its working and inoperative positions. The partition T may be flat or wedge-shaped as shown. In a battery of cells the chamber which receives the electrolvte when not in use may be situated beyond the ends of the electrode plates P, Z, instead of being at one side thereof. The soluble electrode Z may be of zinc and may be provided at its upper end with a socket for a supporting screw S passing through a cover d. Two lead-peroxide plates P mav be supported at one end of the cell by lugs and at the other by a common contact head. Dilute sulphuric acid is a suitable electrolyte. The cover d of acid-proof insulating- material may be pressed against a gasket G in the thickened rim of the cell by a metal plate E engaged by screws D in clamp bars K which take under the rim. A gas exit consists of a vessel V provided with narrow upright gas inlet and outlet tubes and with side holes l for return of liquid. A battery of such cells may be employed in a portable lamp, which can be switched on or off by simply tilting and returning the whole lamp.

IPC: D05B57/02
Abstract: 115,221. Thompson, W. P., (Union Special Machine Co.). Jan. 15, 1917. Multiple-needle machines; double-loop stitching; work-supports.-Relates to sewing-machines of the type having needles co-operating with threaded loopers and consists in the means for spreading the loops of the under thread for the passage of the needles. The needle hole 69 is provided with an extension in the direction of feed having an inclined face 71 and a shoulder 72.

Patent GB-1037893-A (GB)
Title: New active substances and their manufacture
IPC: C07K7/64
Filed: 1964-03-23
Abstract: The invention comprises derivatives of ferrichrysin of formula <FORM:1037893/C2/1> and of desferrichrysin of formula <FORM:1037893/C2/2> where R1 is hydrogen or an acyl group and R2 is an alkyl group containing 1 to 6 carbon atoms when R1 is a hydrogen atom.  The derivatives are prepared either (a) by reacting ferrichrysin with an acylating agent, and, if desire, removing iron from the resulting compound; or (b) by desacetylating desferrichrysin in an acid medium, reacting the resulting cyclic hexapeptide with an acylating agent other than an acetylating agent, selectively splitting off the O-acyl groups, and, if desire, converting the resulting desferri compound to the corresponding iron-containing complex compound by means of ferric ions.  In examples ferrichrysin is acylated with acetic anhydride and the resulting O,O1-diacetyl-ferrichrysin is converted to the desferri compound by reaction with 8-hydroxyquinoline; and desferrichrysin is des-acetylated by heating with hydrochloric acid, acylated with propionic anhydride and with bytyric anhydride, and the products reacted with ferric chloride.

The snare proper comprises two lengths of wire e, f, secured to each other at their ends by linke i, i<1> and each being bowed in the middle and passing two or more times round a pivot pin h so as normally to take up the position shown in Fig. 3, a freely sliding ring K encircling the wires where they cross each other. The extreme lower ends of the wires e<2>, f<2> are bent back at right-angles, and coiled springs j, j<1> are mounted on the bent-back portions, the free ends of the springs being continued to form handles j<4>, j'. In setting the trap, the ends e<2>, f<2> of the wires are forced together so that the noose space g is widened, and the springs j, j<1> are inserted in the pockets b, the ends c<2>, f<2> being held together by a releasing catch n. The handles j<4>, j<5> of the springs are given a turn and secured against projections on the base. The springs tend to turn the snare upwards about the axis of the springs, but this tendency is restrained by a trip lever l on the base passing over the crossing of the wires c, f and engaging under a projection m on the tread-plate d. When the trip-lever is released by an animal stepping on the tread-plate, the snare swings upwards about the axis of the springs until the catch n engages and is detached by a short post c. The wires e, f then spring outwards, securing the animal in the noose part g. In a modification, the wires may be rigid and the links i, i<1> replaced by springs. In another modification, the noose portion g is caused to contract by springs round the pivot pin h.
